SHUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 636,720, dated November '7, 1899.

Application filed November 25, 1898. Serial No. 697,454. (No model.)

To all whom it may concern.-

Be it known that I, OBED DE CHAMP, of Everett, in the county of Middlesex andState of Massachusetts, have invented certain new and useful Improvements in Blind or Shutter Workers, of which the following is a specification.

This invention relates to improvements in shutter or blind workers of that class in which the shutter or blind is turned upon its hinges from the inside of the window to open or close said shutter or blind without necessitating the opening of the window; and it consists of the novel construction, arrangement, and combination of parts substantially as hereinafter described and claimed.

The invention is carried out substantially as illustrated on the accompanying drawings, which form an essential part of this specification, and whereon- Figure 1 represents an exterior view of a portion of a window-casing and a blind, showing my improved shutter or blind worker applied thereto. Fig. 2 represents a vertical section on the line A B shown in Fig. 1. Fig. 3 represents a horizontal section on the line C D, also shown in Fig. 1. Fig. 4 represents a similar view to that of Fig. 3, showing my invention when applied to work double blinds which are hinged together and which fold upon each other when opened.

Like characters refer to like parts wherever they occur on the different parts of the drawings.

The blind 1 is hinged to the window-casing 2 by means of the ordinary blind-hinge now in common use, which hinge consists of the pin-bracket 3, secured to the window-casing, and the socket portion 4, secured to the blind, said socket portion being adapted to receive the pin 5 of the pin-bracket in such a manner that the socket portion is free to rotate on said pin during the opening and closing of the blinds.

My improved blind-worker is designed more ;especially to be used in connection with a blind-hinge, substantially as above described; and it consists of a segmental pulley 6, which is placed upon the pin 5 of the blind-hinge preferably before the socket portion of the hinge is placed thereon and so that it can rofate on said pin. The portion of the pulley which is removed therefrom is V-shaped and is of sufficient size to allow the pulley to embrace the corner of the blind and to rest against the front and one edge of the blind in such a manner that when said pulley is turned upon the pin 5 it will cause the blind to be turned upon its hinges.

To prevent any swinging movement of the blind within the V-shaped cut-away portion of the pulley, I provide the pulley with a perforation 7, and provide the blind with an attached downward-projecting pin 8, which enters said perforation and tends to firmly attach the pulley and blind together when the blind is hung on its hinges. The blind, with the attached socket portion 4 of the hinge and its attached pin 8, may be unhiuged and removed, leaving the pulley 6 remaining on the pin 5.

A chain, cord, or tape 9 is attached to the rim of the pulley 6 at one side of the V-shaped cut-away portion, and a similar chain, cord, or tape 10 is attached to the rim of the pulley at the opposite side of the V-shapedcutaway portion. On the drawings I have illustrated the use of chains. These chains are carried in opposite directions upon the rim of the pulley, which is grooved to receive them, and are then carried backward through the respective tubes 11 and 12, which are inserted through the window-casing from outside to inside. The inner ends of the chains 9 and 10 are preferably providedwith the respective knobs, rings, or other suitable enlargements 13 and 14, which act as handles to manipulate the blinds and also as stops to prevent the chains being accidentally drawn through the tubes. The chains 9 and 10 are provided with the respective plugs or pistons 15 and 16, which are located within the tubes 11 and 12 and tend to close said tubes against the admission of air or insects, although they can be reciprocated freely within the tubes when the chains are moved to work the blinds, as hereinafter described.

A plate 17 is secured to the outside of the window-casing, which plate has perforations to correspond with the tubes 11 and 12, and is also preferably provided with the rolls 18 and 19, upon which the chains 9 and 10 move in order to cause their easy movement. A second plate 20, having perforations thereon to correspond with the tubes 11 and 12, is secured to the inside of the window-casing, so that the perforations in it register with said tubes. This plate 20 is provided with a projecting ledge 21, having notches 22 22, one for each chain 9 and 10, and into which the chains are placed, substantially as shown in Fig. 2, in order to prevent them from moving in the tubes and in order to lock the blind in any desired position, as will be described hereinafter.

It is the intention to place the tubes 11 and 12 at such a distance from the blind-hinge that they will pass through the studding of the building and not enter the weight-box or interfere with the working of the windowweights.

With the blinds closed, as shown on the drawings, the operation of my invention as thus far described is as follows: If it is desired to open the blind, the person in the house grasps the knobs 13 and 14, and by drawing them toward him and from the easing withdraws the chains from the notches 22 and by this means unlocks the chains, so that they will be free to be moved inward or outward in the tubes 11 and 12. He then draws the chain 9 inward through the tube 11 and at the same time allows the chain 10 to move outward through the tube 12. As the chain 9 rests within the groove on the outside of the segmental pulley G and is attached near the outside of the V-shaped cutaway portion of the pulley, it will be seen that the drawing of the chain 0 inward through the tube 11 will cause the pulley, with its connected blind, to be turned upon the hinge-pin 5, so as to open the blind, while at the same time the chain 10, resting within a groove on the inside of the pulley and being attached near the inside of the V-shaped cut-away portion of the pulley, will be drawn outward through the tube 12 by this movement of the pulley upon the pin 5. The blind may be locked at any position between a closed or an open position, as well as be locked at both a closed or open position, by both of the chains 9 and 10 being drawn taut and one of the links in each chain being inserted within the respective notches 22. If it is desired to close the blinds, the reverse of the above operation is performed.

WVhen double blinds hinged together, as shown in Fig. 4, are used with my improved worker, I provide the outer blind with a rod or bar 23, which is pivotally attached at2et to the lower side of the blind and is also pivotally attached at 25 to the window-sill, the bar being provided with a slotted perforation 2G by which it is free to move upon-said pivotal connection 25. By connecting the outer blind to the window-sill by means of the rod 23 and hinging said outer blind to the inner blind, as shown, I am able to open or close both blinds by the operation of my improved worker, which acts directly upon the inner blind and through said innerblind upon the otherblind, so as to make them work in unison.

It will be understood that I do not wish to confine myself to the use of chains alone, whereby the pulley may be turned upon the hinge-pin, as a cord, wire, or tape may be substituted therefor, if so desired. Neither do I wish to confine myself to the use of the tubes within the perforation through which the chains are guided, as the plates on the outside and inside of the casing of the window may snffice to act as guides for the chains which operate the blinds.

Havingthus fully described the nature,construction, and operation of my invention, I wish to secure by Letters Patent and claim- 1. In a blind or shutter worker, the combination with the ordinary hinge consisting of a pin-bracket on the building and a socket portion on the blind or shutter, of a pulley provided with an angular cut-away portion to embrace the corner of the blind or shutter, said pulley placed loosely upon the pin of the bracket and rotatable thereon, and means substantially as described to cause the rotation of said pulley on the hinge-pin to open or close the blind or shutter, whereby the worker may be applied to blinds or shutters without a change or injury to their existing hinges, and the blinds or shutters may be removed without disarrangement of the workers, for the purpose set forth.

2. In a blind or shutter worker the combination with the ordinary hinge consisting of a pin-bracket on the building and a socket portion on the blind or shutter, of a pulley provided with a cut-away portion to embrace the corner of the blind or shutter, said pulley placed loosely upon the pin of the bracket and rotatable thereon, and chains attached to the pulley and guided in opposite directions upon the rim of the pulley, and through the casing of the window, whereby the worker may be applied to blinds or shutters without change or injury to their existing hinges, the blinds or shutters may be worked by the manipulation of said chains and may be unhinged leaving the worker in proper working order at any time, for the purpose set forth.

3. In a blind or shutter worker, the combination with the ordinary hinge consisting of a pin-bracket on the building and a socket portion on the blind or shutter, of a pulley provided with an angular cut-away portion to embrace the corner of the blind or shutter, said pulley placed loosely upon the pin of the bracket and rotatable thereon, means substantially as described to cause the rotation of said pulley on the hinge-pin to open or close the blind or shutter, a pin attached to the blind or shutter and a perforation in said pulley to receive said pin, whereby the blind can be easily removed from the hinge -'bracket leaving the worker intact mounted upon the hinge-pin, and whereby the blind or shutter will be held rigidly within the cut-away portion of the bracket, for the purpose set forth.

4. In a blind or shutter worker of the class described operated by movements of chains 85c. through perforations in the casing of'the window, plugs or pistons on said chains and movable inward and outward within the perforations in the window-casing, to prevent [0 the admission of air or insects through said perforations, and whereby the blind or shutter may be removed from the hinge-pins leaving the blind or shutter worker intact for the purpose set forth.

In testimony whereof l have aflixed my sig- I 5 nature in presence of two witnesses.
